Diseño y caracterización de un enfriador de átomos de tipo “desacelerador Zeeman”
(2016)
Nosotros presentamos un método que utiliza simultáneamente dos modelos matemáticos, con el objetivo de optimizar el diseño de un desacelerador Zeeman, con miras a la implementación de átomos ultrafríos a la física del ...
Converging science and literature cultures: learning physics via The Little Prince novella
(2018)
Primary level education follows a pedagogy model where literature and science have been historically separated. Natural children processes are disrupted, as learning based on play curiosity is completely transformed by a ...
Lamellar fluctuations melt ferroelectricity
(2023)
We consider a standard Ginzburg-Landau model of a ferroelectric whose electrical polarization
is coupled to gradients of elastic strain [1–4]. At the harmonic level, such flexoelectric interaction
is known to hybridize ...
Study of oxide bands in p-type porous silicon layers
(2019)
The interest in developing fast and reliable chemical and biochemical sensors in an inexpensive way is something that has attracted a lot of efforts in the last decades. One of the potential material candidates is ...
Pressure dependence of ferroelectric quantum critical fluctuation
(2019-12-13)
Phase transitions to a long-range-ordered state driven by a softened phonon mode are ubiquitous across condensed matter physics, but the evolution of such a mode as the system is tuned to or from the transition has never ...
Energy exchange between atoms with a quartz crystal μ-balance
(2018)
We propose an experimental method to fully characterize the energy exchange of particles during the
physical vapor deposition (PVD) process of thin surface layers. Our approach is based on the careful
observation of ...
Vacuum treatment to stabilize oxidation at low temperature region in porous silicon
(2020)
Oxidation in porous silicon is studied for as-etched samples and samples subjected to high vacuum at room temperature. Attenuated Total Reflectance (ATR) measurements in infrared spectroscopy for temperatures ranging from ...
Negative thermal expansion near two structural quantum phase transitions Connor
(2017-12-18)
Recent experimental work has revealed that the unusually strong, isotropic structural negative thermal
expansion in cubic perovskite ionic insulator ScF3 occurs in excited states above a ground state tuned very near a ...
